Thus, F-sharp and G-flat might sound the same (on a piano at least), but they can have very different functions in actual music. The reason that all these different notes exist which are played by only one key on a piano is that it depends on how a composer uses them. This doesn’t mean that they’re all created equal. These notes (called enharmonic) are “close enough” in pitch that most people couldn’t detect any real difference anyway, so only a single piano key is used for all of them.

Therefore, each possible note in Western music corresponds to one key on a piano, and in fact many different notes correspond to the same key. The piano would be impossible to play if it had separate keys for all the flats, sharps, double flats and double sharps. Hence, the first key in the chart could be C or B-sharp, or it could be D double flat or even A triple sharp! In fact, technically speaking there’s no limit to the number of notes that correspond to a given key on a piano. You’ll notice that each key has two different note names in the chart. If you only learn one thing about the piano key chart, make sure it’s this: The keys are not the notes (see Layout of Piano Keys).

(Double sharps and double flats have been omitted, since the chart would otherwise get too confusing and do more harm than good.) If you’re just getting started, you might wish to start with the Piano Notes Chart… but be sure to return here! The chart includes naturals (C, D, E, F, G, A, B), flats and sharps. If you’re just learning to find notes on the piano keyboard, this basic piano key chart is designed for you.
